Even if the open-enrollment period has passed for signing up for insurance via one of the exchanges, you might still be able to purchase subsidized insurance if you've had a qualifying life event. Qualifying events include moving to a new state, change in income, change in family, loss of coverage and others. You may even be able to apply simply because you did not understand that open-enrollment ended or you did not understand the health care law. If your income qualifies you for subsidized health care, you'll want to purchase through your state exchange.
Being in the business for a very long time, I have found that most people are clueless about insurance, even most agents who sell them. I will agree that their rates are cheap. But I wouldn’t recommend them. Inexperienced adjusters. They do not fully investigate. The policy does not cover like, kind, and quality which is bad if you have a new vehicle.
